About N5

N5 Sensors’ mission is to keep people safe from environmental hazards through a cloud-connected ecosystem of smarter sensors and by leveraging the endless possibilities of shared data and AI.

N5 Sensors’ advanced wireless sensor network equips communities, farms, cities, utility companies, and local government and fire departments with early detection and 24/7 alerting system. Our real-time early warning system (less than 5 minutes from ignition) empowers first responders to respond to wildfires faster, and keep their communities safe.

Our Story

N5 was founded in 2012 as a spin-off from the University of Maryland, College Park. We are passionate about developing sensor technologies and products that will make your life better and safer. By bringing together technological innovation and reliable engineering, we are changing how sensing is done. In this new era of wearables, smart-homes, and connected cities, our products will open up new possibilities, giving people the ability to learn about their environment and understand its impact on their health and well-being.

“A team is more than a collection of people. It is a process of give and take.”

Co-Founder & CEO PFP Cybersecurity

Steven Chen

Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth.
